により連通した構成となつていた。Structure of conventional example and its problems As shown in Fig. 1, this type of conventional combustion apparatus has a burner frame 1 made of extruded aluminum material, a mixture chamber 2 in the center, and a flame port 3 on the downstream side. A fixing groove is provided, and a recess and an air chamber 5, which constitute a part of a flame holding chamber 4, are formed on both sides of the flame port 3. On the downstream side of the air chamber 5, an air jet plate 8 having a flame holding port 6 and a short flame port 7 is fixed by fixing grooves 9, 9', and the air chamber 5 and the flame holding chamber 4 are provided on the air jet plate 8. Convex part 1
A small gap 11 formed between the burner frame 1 and the burner frame 1 due to
The structure was designed to communicate with each other.

など特別な工夫を必要とした。 In this case, it is possible to downsize the entire device with a combustor with a small combustion volume, such as a heater, but this configuration cannot be applied to a large combustor with a combustion volume of 2 to 3 times or more, such as a large water heater. The flame opening part 3 is also 2~
It had to be more than three times as long, which was very inconvenient in terms of the overall configuration of the device. In addition, if the above-mentioned problem is simply provided with the flame port 3, the temperature of the air jet plate sandwiched between the flame ports on both sides will rise abnormally due to the flames formed on both sides, resulting in a durability problem. It was hot.
Furthermore, since it was extremely difficult for the flame to transfer between the flame ports when ignited, special measures were required, such as installing a fire transfer plate between the two flame ports.

130度と構成したものである。Structure of the invention In order to achieve this objective, the present invention uses extruded aluminum material on both sides of the flame nozzle to prevent the mixture from being injected into the combustion chamber from the flame nozzle, which is formed by providing a large number of flame nozzles in a straight line. A molded air chamber is provided, and the air chamber has a flame stabilizing part with a large number of flame stabilizing ports that eject air almost parallel to the flow direction of the mixture, and a flame holding part that ejects air at an angle in the flow direction of the mixture. An air jet plate having a large number of short flame ports arranged in a zigzag or conical shape in the longitudinal direction of the flame port forms a part of the air chamber. The air injection plate of the air chamber, which has a plurality of arranged flame ports on both sides, is formed into a mountain shape and has a flame holding part and a short flame part on both sides, and the short flame part and the end face of the flame mouth part on the combustion chamber side. The angle to be made is 100~
The angle is 130 degrees.

ることはなくなる。 With this configuration, the mixture jetted into the combustion chamber from the multiple flame ports gently mixes with the air jetted and supplied in parallel from the flame holding ports, forming a stable flame on both sides of the flame port. This stabilizes the entire flame. Furthermore, on the downstream side, the combustion reaction is promoted by forced mixing with the air that is ejected and supplied from the short flame port at an angle, thereby realizing a short flame. Here, the short flame ports are arranged in a zigzag or square shape, so the flame is formed along the short flame ports, so the flame is continuously formed up to the downstream side of the air injection plate. . Furthermore, the angle between the short flame part and the end face of the flame mouth part on the combustion chamber side is
Since the angle is 100 to 130 degrees, flames are formed continuously from both sides to the downstream side along the air jet plate that has flame ports on both sides, and the flames are intermittently formed between each other. be in close proximity. Further, the amount of air ejected from the flame holding port of the air injection plate having flame port portions on both sides is configured to be larger than the amount of air ejected from the flame holding portion of the air injection plate having flame port portions on only one side. If this is done, the flame attached to the short flame opening will separate due to the parallel air flow in the flame holding part, and will no longer directly heat the air injection plate.

is a fan that supplies combustion air, which is divided into primary air supplied into the mixing pipe 14 facing the nozzle 13 on the downstream side, and secondary air supplied into three air chambers further downstream. . The burner frame is made of aluminum extrusion and has a central air chamber 1.
A mixture chamber 17 is formed between the air chamber 5 and the side air chamber 16. This burner frame has a flame opening part 1.

A short flame section is integrally formed with a large number of short flame ports 23 arranged in a zigzag or square-shaped shape in the longitudinal direction of the flame port section 18. Further, a small protrusion 24 is provided between the flame holding part and the short flame part, and the air chambers 15 and 16 and the flame holding chamber 19 communicate with each other through a small gap formed between the burner frame and the air injection plate 20. . Further, the air injection plate of the air chamber 15 having the flame opening portions 18 on both sides is configured in a chevron shape, and has a flame holding portion and a short flame portion on both sides, and an angle formed between the short flame portion and the end surface of the flame mouth portion on the combustion chamber side. θ is set at 100-130°.

The combustion air supplied by 2 flows into the mixing pipe 14 due to the ejector effect of the fuel ejected from the nozzle 13.
The air is divided into primary air that is drawn into the chamber and secondary air that is supplied to three air chambers located further downstream. The air-fuel mixture exiting the mixing tube 14 is guided to two air-fuel mixture chambers 17, straightened by a pressure equalizing plate 21, and then ejected into the combustion chamber from the flame port 18. On the other hand, air chamber 1
The secondary air supplied into the chambers 5 and 16 is rectified by the pressure equalizing plate 21, and a part of the air is depressurized through the gap, reaches the flame holding chamber 19, and flows out from both sides of the flame port 18 at a low speed through the flame holding port 22. This contributes to stabilizing the flame base. Most of the secondary air is obliquely supplied to the air-fuel mixture from both sides through the short flame ports 23, and by promoting the combustion reaction through forced mixing, a short flame is achieved and the device is made more compact.

傾向にあり、θが大きくなるとその逆の傾向とな

が最も良い。 Now, the short flame ports 23 are arranged in a zigzag or square-shaped shape along the longitudinal direction of the flame port 18, and the flame F is arranged along the arrangement of the short flame ports 23 as shown in FIG. Therefore, a continuous flame F is formed up to the downstream side of the air injection plate 20. Also, an air injection plate 20 of the air chamber 15 having flame ports 18 on both sides.
As shown in FIG. 5, the angle θ formed between the short flame part and the end face of the flame mouth part is closely related to combustion performance, noise, and flame transfer performance. That is, if θ is small, the flame F will be short and the combustibility will be improved, but the noise will be louder, and the distance between adjacent flames F formed along the air jet plate to the downstream side will increase, making it difficult for fire to spread. There is a tendency that the opposite tendency occurs as θ increases. Judging from these comprehensively, θ of 100 to 130 degrees is best.

By making the height of the flame holding port 22 larger than that of the air jet plate 20 of the air chamber 16, the amount of air in the flame holding port 22 can be increased. The air blowing plate 20
temperature can be lowered.
